Know About CDN Services

Content Delivery Networks (CDN) is a collection of web servers located at different points within the network, in order to maximize the bandwidth and deliver content more efficiently for other network users. The geographical proximity of the closest server, or less response time is usually selected.

Using a CDN can be expensive, but the site grows and attracts more traffic around the world, it is necessary to use a CDN to reduce response times.

Web sites that generate millions of impressions per day own their own CDN, but for the small business owner, it is more cost effective to use a CDN service provider.

There are several companies offering web hosting services. All work seamlessly behind the servers that are well known to the general public:

Akamai: One of the largest CDN in the world, working with Akamai mirrors content. This can include all data from a website, including text, graphics, animation or video, or simply files the media. The Akamai server is chosen based on the user’s location and type of site content. Some of Akamai’s customers include Apple, Yahoo, Adobe Systems, and JC Penney.

Limelight Networks: The main rival Akamai, Limelight has existed since 2001. Limelight operates via fiber optic networks, eliminating the burden and the traffic on the public Internet. Just a couple of Limelight customers include Facebook, MySpace, Netflix, MSNBC, Fox News, PlayStation Network and Xbox.

Amazon Cloud Front: Provides the Amazon Web Services, before the cloud has been created to compete with Akamai and Limelight Networks. Front cloud is the servers are located in Europe and Asia, as well as the United States. It is a pay-as-you-go, which allows to test the service without any commitment to the agreement.

Peer-to-Peer CDN

Peer-to-Peer (P2P) content distribution have been the focus of media attention a few years ago, our customers have used these peer-to-peer file sharing copyrighted material illegally. P2P CDN known examples are Napster, Kazaa and The Pirate Bay. Despite the abuse, the use of PSP CDN to distribute large files without caching the data on your network. P2P users with data easy – when you download the file, the user acts as a server “seeding” the file (the file to be downloaded by other users).

The two main problems with P2P is the lack of quality (HD) and the ability of users to manipulate files by adding malware. The lack of quality is not the fault of the system, but due to the fact that the majority of P2P users do not have strong enough Internet connections to download or send high-definition video without the process taking several hours or days.

CDNs Free

Most companies providing CRC without operating through P2P. Despite P2P can help reduce pressure on your server if you have coveted (and original, of course) files on the media, not static content spread multiple geographic locations, and therefore do not offer same quality of service and Limelight, Akamai and Amazon CloudFront.

Without CDN

CDN to lighten the source server for the different points of the communication network. Without CDN would not be a bottleneck very extreme and visited sites like Facebook, CNN, and Google would take forever to reach. If the Internet is the information highway, CDN working on alternative routes to the same destination, avoiding traffic jams of mass, and more convenience.
